Description
Technical field
The present invention relates to a kind of fluid-cooled electrical machine.
Background technology
Guarantee motor for the temperature rise that reduces motor in the prior art and normally stably work, cooling device is installed on the motor mostly, described cooling device generally is divided into two kinds of air-cooled and liquid cooling.Air cooling equipment is because noise is very big, and cooling effectiveness is not high, uses not extensive.Liquid cooling apparatus is owing to its noiselessness, cooling effectiveness height are widely used.The liquid cooling apparatus that fluid-cooled electrical machine of the prior art adopts all is to adopt integral structure to be fixed on the shell of motor.Two kinds of the most frequently used mounting meanss are hot jacket and welding, and so-called hot jacket is inserted on the motor housing after allowing it expand the cooling device heating exactly, thereby allows its cooling make it to tighten non-disconnectable being fixed on the motor housing again; Welding then is directly that the cooling device weldering is dead on the shell of motor.Though it is easy to process that cooling device is fixedly connected on the motor housing, cooling device also is not easy to leak, and it is more stable to work.But the medium that liquid cooling apparatus adopts generally is water and oil.Because the low price of water, water-cooled is more common, take by the water cooling plant as example: from known, the words that water and metal contact for a long time, the metal surface can produce incrustation scale, and the principle of liquid cooling apparatus be exactly in the motor housing setting around the circulatory flow of motor housing, make liquid in runner, circulate to take away heat on the motor.It is not very big that the bore of runner is subjected to spatial limitation, can accumulate very thick incrustation scale in the runner after motor uses a period of time, and incrustation scale can cause runner to stop up, and causes realizing the circulation cooling; Be exactly that incrustation scale is even without runner is stopped up in addition, cooling water can not directly be contacted with motor housing fully, because incrustation scale is attached to the motor housing surface, form a structure that is similar to heat-insulation layer easily, cause the cooling effectiveness of liquid cooling apparatus to reduce, the appearance of above-mentioned two kinds of situations makes the user often need the runner in the cleaning water cooling plant, and whole motor housing and water cooling plant are because non-disconnectable, can cause erosion to motor housing and cooling device again if adopt chemical method to clear up incrustation scale, so often can only change whole motor housing and water cooling plant.Same if the oil cooling device, often contain various impurity in the cooling oil, the situation of the impurity obstruction coolant flow channel in the oil in use also can appear in motor, at this moment also needing to pull down cooling device clears up, oil cooling device of the prior art is non-disconnectable, and the user also can only change whole motor housing and oil cooling device.In sum, fluid-cooled electrical machine of the prior art exists the runner cleaning of cooling device inconvenient, the weak point that causes runner to stop up easily.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of runner cleaning of cooling device very convenient, is not easy the fluid-cooled electrical machine that causes runner to stop up.
For solving the problems of the technologies described above, technical scheme provided by the invention is: a kind of fluid-cooled electrical machine, it comprises motor housing, on the described motor housing liquid cooling apparatus is installed, liquid cooling apparatus comprises upper outlet body and the lower cover that is equipped with fluted flow channels on the inwall, on the outer wall of motor housing, the fluted flow channels in upper outlet body and the lower cover interconnects and runner is provided with inlet and liquid outlet by the locking device obvolvent for described upper outlet body and lower cover; The junction of upper outlet body and lower cover is provided with sealing device, is provided with sealing device between the two ends of the liquid cooling apparatus that upper outlet body and lower cover obvolvent form and the motor housing.
After adopting above structure, the present invention has following advantage: liquid cooling apparatus comprises upper outlet body and the lower cover that is equipped with fluted flow channels on the inwall, on the outer wall of motor housing, the fluted flow channels in upper outlet body and the lower cover interconnects and runner is provided with inlet and liquid outlet by the locking device obvolvent for described upper outlet body and lower cover; The junction of upper outlet body and lower cover is provided with sealing device, is provided with sealing device between the two ends of the liquid cooling apparatus that upper outlet body and lower cover obvolvent form and the motor housing.Liquid cooling apparatus adopts the removable structure of Hafu type, can also dismantle very easily when guaranteeing sealing effectiveness and heat dispersion, the user can regularly take liquid cooling apparatus apart and clean the unimpeded of the interior incrustation scale of runner and impurity assurance runner and be in best radiating state.
As preferably, described upper outlet body is square upper outlet body, described lower cover is square lower cover, both are the square foundry goods that one side has the semi-circular breach that the outer wall with motor housing is nested, described fluted flow channels is arranged on the inner surface of described breach and is communicated with inlet and liquid outlet on the runner, the two ends of square upper outlet body and square lower cover by screw lock on motor housing, the middle part of square upper outlet body and square lower cover is by the clip obvolvent, the junction of square upper outlet body and square lower cover is provided with seal groove, seal groove is provided with sealing ring, is provided with sealing ring between the two ends of square upper outlet body and square lower cover and the motor housing.Square foundry goods is simultaneously slotted, and can pass through the mould one-shot forming, the processing technology simple and fast, and two ends fix with screw, and middle by the clip obvolvent, combination seal coil structures good seal performance, dismoutability is also fine.
As further preferred, described inlet and liquid outlet lay respectively at the two ends of runner, and the runner between described inlet and the liquid outlet is helical groove structure.Hickey can be connected on the external circulation circuit very easily, and can there be the blind area in the helical groove structure fluid in order in that internal flow is smooth and easy more.
Preferred as another kind, described upper outlet body is semi-circular upper outlet body, and described lower cover is semi-circular lower cover, and both are foundry goods and inwall is provided with fluted flow channels, be communicated with inlet and liquid outlet on the described runner, the runner between inlet and the liquid outlet is helical groove structure; Also be provided with hollow slots on the outer wall of two cover bodies.Semi-circular structure has been saved cost to greatest extent in conjunction with the hollow slots on the outer wall, and the hollow slots on the outer wall has enlarged the cooling surface area of outer wall in addition, and the effect of radiating fin is arranged, and has further strengthened the radiating effect of liquid cooling apparatus.
